Cannabis use in a sample of Aristotle University of Thessaloniki students: a pilot cross-sectional study

Cannabis is the most widespread illicit drug among young adults globally. This study aimed to detect the extent of cannabis use in the study population and its impact on users' lives. We hypothesized that early cannabis use would significantly predict later high-risk use.

An online cross-sectional study using a self-administered questionnaire was conducted in December 2021, aiming to explore the extent of cannabis use among students and detect changes in behavior and impact on their lives. The results were analyzed statistically and correlated.

Out of the 297 enrolled participants with a mean age of 21.0 ± 2.1 years, 101 (33.9 %) had used cannabis at least once (50 males). The mean age at first cannabis use was 18.5 ± 2.11 years. Over 90 % reported easy access to it. Behavioral changes following use were reported by 41.6 %, but none except one sought help. Age at first cannabis use was negatively correlated with past-month and past-year use. Cannabis use before midday was positively correlated with age on the first try.

The prevalence of cannabis use was higher than the European average. Confirming the study's hypothesis, the younger the age at first use, the heavier the past-year and past-month use, which also agrees with previous studies. Cannabis consumption before noon was linked to increased use, and alarmingly, there was reluctance to seek help despite a high proportion of behavioral changes after use.

As the legislation on the use of cannabis changes rapidly, and given the increasing popularity of cannabis, there is a need for continued research on how various factors differentially impact its use. HIPPOKRATIA 2021, 25 (4):162-168.
